SAFe® for DevOps Practitioners

Overview of this book

Product development and release faces overlapping challenges due to the combined pressure of delivering high-quality products in shorter time-to-market cycles, along with maintaining proper operation and ensuring security in a complex high-tech environment. This calls for new ways of overcoming these challenges from design to development, to release, and beyond. SAFe® for DevOps Practitioners helps you use a DevOps approach with the Scaled Agile Framework and details how value streams help you resolve these challenges using examples and use cases. The book begins by explaining how the CALMR approach makes DevOps effective in resolving product development roadblocks. Next, you’ll learn to apply value stream management to establish a value stream that enables product development flow, measure its effectiveness through appropriate feedback loops, and find ways of improving it. Finally, you’ll get to grips with implementing a continuous delivery pipeline that optimizes the value stream through four phases during release on demand. This book complements the latest SAFe DevOps courses, and you’ll find it useful while studying for the SAFe DevOps Practitioner (SDP) certification. By the end of this DevOps book, you’ll have gained a clear understanding of how to achieve continuous execution and release on demand using DevOps and SAFe.

Developing the solution

Teams on an ART work in markedly different ways than those that worked in product development using waterfall methodologies. An emphasis on Lean thinking and a focus on the system dictates newer ways of working.

We will examine the following aspects of engineering practices that are used by Agile teams today:

  • Breaking down the work
  • Collaborative development
  • Building in quality
  • Version control
  • Designing to the system

These practices strive to allow for a continuous flow of work, ready for the next state of building.

Breaking down into stories

An important part of the Lean flow we picked up on in Chapter 4, Leveraging Lean Flow to Keep the Work Moving, was to keep batch sizes small. A feature, as presented to us before PI planning, is a large batch of work, meant to be completed by the end of the PI. In order to ensure a smooth flow of work, the feature must be broken down into smaller batches of work.
